Iodine Selenium supplements are a combination of two essential minerals that are crucial for maintaining healthy thyroid function and overall well-being. Iodine helps to regulate the production of thyroid hormones, while selenium acts as a powerful antioxidant that supports immune function and protects against oxidative damage. These supplements are particularly beneficial for individuals with thyroid disorders, as well as those who are deficient in these minerals due to dietary restrictions or environmental factors. With regular use, iodine selenium supplements can help to improve energy levels, support healthy metabolism, and promote optimal health and wellness.

Frequently Asked Questions (FAQs)

1. Should you take iodine with selenium?

INTRODUCTION. Adequate intakes of both iodine and selenium are required for optimal thyroid function (1–3). Iodine is an essential component of the thyroid hormones thyroxine (T4) and triiodothyronine (T3), and deficiency will impair synthesis of these hormones.

2. What is selenium and iodine good for?

Micronutrients, mostly iodine and selenium, are required for thyroid hormone synthesis and function. Iodine is an essential component of thyroid hormones and its deficiency is considered as the most common cause of preventable brain damage in the world.

3. Is iodine and selenium the same?

Iodine is the main component of thyroid hormones, namely, thyroxine (T4) and triiodothyronine (T3). Selenium is present in the thyroid gland in high concentrations, and this suggests that selenoproteins may contribute significantly to the integrity and functioning of the gland.
